摘要：

为了满足新能源车辆对轻量化及高强度的严苛要求，提出将高强度钢板与CFRP预浸料组成Steel/CFRP复层材

料，通过两种异质材料的匹配设计和优势互补，实现车体承力件轻量化新思路。针对Steel/CFRP，提出适用

于轻量化Steel/CFRP车体构件高效量产的混合热共冲工艺，阐述了其工艺原理及特点；设计开发了用于

Steel/CFRP复层材料盒形件混合热共冲成形工艺试验用的可加热温控模具，介绍了其结构组成及主要零件。

开展了相应的工艺试验，证明了所提出Steel/CFRP复层材料构件混合热共冲工艺方案的可行性和有效性，为

后续对Steel/CFRP构件混合热共冲过程中材料的成形性能、变形行为、界面结合状态及安全性、吸能性研究

，提供了必需的实验样品。

To meet lightweight and high-strength demands of new energy vehicles, a new lightweight idea

for the load-carrying parts was put forward by combining high strength steel metal with CFRP

prepregs to form Steel/CFRP laminate materials, which is a matching design that has

complementary advantages. For the above Steel/CFRP laminate materials, a combined hot stamping

process was proposed to implement the efficient mass production of lightweight Steel/CFRP

automotive components. Then, the corresponding process principle and feature described. In

addition, a set of die, whose temperature and heating rate were controllable, was designed to

implement the combined hot stamping of Steel/CFRP boxlike parts. And the mold structure and

its main parts were introduced. Finally, the related process experiments were conducted. The

experimental results show that the feasibility and validity of the proposed process are

verified, and the study provides necessary test samples on formability, deforming behavior,

interface bonding status, security and energy absorption capability, etc. of Steel/CFRP

laminate materials for follow-up investigation.
